Before weekly sales and my coupons my total was $171.49
equals $14.07 before Tax
saving $157.42 or a 91.8% savings

my First transaction was $3.74 Second was $1.78, Third was $5.94 and my fourth was $7.25

So My Total was $18.71 - It figures out to be about 22 cents an item

My Mom also went with me and bought almost all the same items and a few things  for super bowl (Chicken wings, yogurt and a few other things) and she spent about $25
